Torsion of Meckel's diverticulum as a cause of small bowel obstruction: A case report

Axial torsion and necrosis of Meckel's diverticulum causing simultaneous mechanical small bowel obstruc-tion are the rarest complications of this congenital anomaly. This kind of pathology has been reported only eleven times. Our case report presents this very unusual case of Meckel's diverticulum. A 41-year-old man presented at the emergency department with complaints of crampy abdominal pain, nausea and re-tention of stool and gases. Clinical diagnosis was small bowel obstruction. Because the origin of obstruction was unknown, computer tomography was indicated. Computed tomography(CT)-scan revealed dilated small bowel loops with multiple air-fluid levels; the oral con-trast medium had reached the jejunum and proximal parts of the ileum but not the distal small bowel loops or the large bowel; in the right mid-abdomen there was a 11 cm × 6.4 cm × 7.8 cm fluid containing cavity with thickened wall, which was considered a dilated bowel-loop or cyst or diverticulum. Initially the patient was treated conservatively. Because of persistent abdominal pain emergency laparotomy was indicated. Abdominal exploration revealed distended small bowel loops proxi-mal to the obstruction, and a large(12 cm × 14 cm) Meckel's diverticulum at the site of obstruction. Meckel's diverticulum was axially rotated by 720°, which caused small bowel obstruction and diverticular necrosis. About 20 cm of the small bowel with Meckel's diverticulum was resected. The postoperative course was uneventful and the patient was discharged on the fifth postopera-tive day. We recommend CT-scan as the most useful diagnostic tool in bowel obstruction of unknown origin. In cases of Meckel's diverticulum causing small bowel obstruction, prompt surgical treatment is indicated; de-lay in diagnosis and in adequate treatment may lead to bowel necrosis and peritonitis.     

Intestinal obstruction caused by torsed gangrenous Meckel’s diverticulum encircling terminal ileum

Meckel’s diverticulum(MD)is considered the most prevalent congenital anomaly of the gastrointestinal tract. It may result in a number of complications including hemorrhage,obstruction,and inflammation.Obstruction of various types is the most common presenting symptom in the adult population.Loop formations with the end of an MD and adjacent mesentery constricting the distal ileum is an uncommon cause of obstruction. Axial torsion and gangrene of MD is the rarest of the complications.The correct diagnosis of complicated MD before surgery is often difficult because this condition may mimic other acute abdominal pathologies.Delay in the diagnosis of a complicated MD can lead to signifi- cant morbidity and mortality.Here we describe the case of a patient with a very rare form of acute small bowel obstruction secondary to giant torsed gangrenous MD encircling the terminal ileum.To our knowledge, this co-occurrence of axial torsion and a loop-forming mechanism of obstruction has been reported only once in English medical literature.     

Trichobezoar: A rare cause of bowel obstruction

A bezoar is an intraluminal mass formed by the accumulation of undigested material in the gastrointestinal tract. A trichobezoar is a bezoar made up of hair and is a rare cause of bowel obstruction of the proximal gastrointes-tinal tract. They are seen mostly in young women with trichotillomania and trichotillophagia and symptoms include epigastric pain, nausea, loss of appetite and bowel or gastric outlet obstruction. We herein describe a case of a trichobezoar that presented as a gastric outlet obstruction and was subsequently successfully removed via a laparotomy.     

Inverted Meckel's diverticulum manifested as adult intussusception: Age does not matter

Adult intussusception due to Meckel’s diverticulum (MD) is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report two cases of intussusception due to MD in adults. A diverticulectomy using a TA stapler was performed in the first patient. In the second patient extensive fibrosis of the adjacent mesentery and thickening of jejunal mucosa were observed, so a segmental resection of the small bowel or affected ileal part and a hand-sewn anastomosis was performed. The postoperative period along with the long term follow-up was uneventful for both patients. The decision between diverticulectomy vs bowel resection can be based on the intussuscepted bowel condition. Early surgical intervention may ensure a favorable outcome.     

Bowel anastomoses: The theory, the practice and the evidence base

Since the introduction of stapling instruments in the 1970s various studies have compared the results of sutured and stapled bowel anastomoses. A literature search was performed from 1960 to 2010 and articles relating to small bowel, colonic and colorectal anastomotic techniques were reviewed. ?eferences from these articles were also reviewed, and relevant articles obtained. Either a stapled or sutured gastrointestinal tract anastomosis is acceptable in most situations. The available evidence suggests that in the following situations, however, particular anastomotic techniques may result in fewer complications: A stapled side-to-side ileocolic anastomosis is preferable following a right hemicolectomy for cancer. A stapled side-to-side anastomosis is likely also preferable after an ileocolic resection for Crohn’s disease. Colorectal anastomoses can be sutured or stapled with similar results, although the incidence of strictures is higher following stapled anas-tomoses. Following reversal of loop ileostomy there is some evidence to suggest that a stapled side-to-side anastomosis or sutured enterotomy closure (rather than spout resection and sutured anastomosis) results in fewer complications. Non-randomised data has indi-cated that small bowel anastomoses are best sutured in the trauma patient. This article reviews the theory,practice and evidence base behind the various gastro-intestinal anastomoses to help the practising general surgeon make evidence based operative decisions.

Management of urethral atrophy after implantation of artificial urinary sphincter:what are the weaknesses?

The use of artificial urinary sphincter(AUS)for the treatment of stress urinary incontinence has become more prevalent,especially in the“prostate-specific antigen(PSA)-era”,when more patients are treated for localized prostate cancer.The first widely accepted device was the AMS 800,but since then,other devices have also entered the market.While efficacy has increased with improvements in technology and technique,and patient satisfaction is high,AUS implantation still has inherent risks and complications of any implant surgery,in addition to the unique challenges of urethral complications that may be associated with the cuff.Furthermore,the unique nature of the AUS,with a control pump,reservoir,balloon cuff,and connecting tubing,means that mechanical complications can also arise from these individual parts.This article aims to present and summarize the current literature on the management of complications of AUS,especially urethral atrophy.We conducted a literature search on PubMed from January 1990 to December 2018 on AUS complications and their management.We review the various potential complications and their management.AUS complications are either mechanical or nonmechanical complications.Mechanical complications usually involve malfunction of the AUS.Nonmechanical complications include infection,urethral atrophy,cuff erosion,and stricture.Challenges exist especially in the management of urethral atrophy,with both tandem implants,transcorporal cuffs,and cuff downsizing all postulated as potential remedies.Although complications from AUS implants are not common,knowledge of the management of these issues are crucial to ensure care for patients with these implants.Further studies are needed to further evaluate these techniques.     

Laparoscopic resection of a giant exophytic liver haemangioma with the laparoscopic Habib 4× radiofrequency device

Haemangiomas are the most common solitary benign neoplasm of the liver with an incidence ranging from 5% to 20%. Although usually small and asymptomatic, they may reach considerable proportions and rarely give rise to life-threatening complications. Surgical intervention is required for incapacitating symptoms, established complications, and diagnostic uncertainty. The resection of haemangiomas demands meticulous surgical technique, owing to their high vascularity and the concomitant risk of intra-operative haemorrhage. Laparoscopic resection of giant haemangiomas is even more challenging, and has only been reported twice. We here report the case of a giant 10 cm liver haemangioma which was successfully resected laparoscopically using the laparoscopic HabibTM 4×, a bipolar radiofrequency device, without clamping major vessels and with minimal blood loss. Transfusion of blood or blood products was not required. The patient had an uneventful recovery and was asymptomatic at 7-mo follow-up.     

肠-腔-房转流术治疗混合型布加综合征的疗效分析

Objective To investigate the therapeutic effect of the meso-cavo-atrial shunt (MCAS) in the treatment of combined Budd-Chiari syndrome (BCS). Methods The clinical data of 17 cases of combined BCS with all or bilateral hepatic vein occlusion and long range occlusion or obstruction of inferior vena cava (IVC) were admitted to the Qilu Hospital from February 2000 to May 2004. All patients were treated by MCAS with artificial blood vessels. The pre- and postoperative clinical symptoms, the IVC and portal venous (PV) pressures, the incidence of postoperative complications and the patency rate of the artificial vessels were analyzed. The survival of patients was analyzed using the Kaplan-Meier analysis, and the data were analyzed using the chi-square test and t test. Results No patient died during the perioperative period, and the symptoms of 15 patients disappeared or were relieved after operation, with a significant difference compared with those before operation (χ2 =9.78, P <0. 05 ). Three patients had complications after the operation. The postoperative PV and IVC pressures were decreased by 1.2 cm H2O (1 cm H2O =0.098 kPa) and 18.5 cm H2O, respectively. There were significant differences in the decrease of IVC and PV pressures ( t = 2.38, 3.06, P < 0.05 ). The 1-, 3-, 5-year survival rates were 16/17, 15/17 and 14/17, respectively, and the 5-year patency rate of the artificial vessels was 14/17.Conclusions MCAS can simultaneously relieve IVC and PV hypertension for patients with combined BCS. The postoperative complication rate was decreased, the 5-year survival rate and the patency rate of the artificial vessels were improved after the treatment, so MCAS is an optional surgical method for treating combined BCS.     

Laparoscopic management of Meckel's diverticulum in children

Background

Rectal bleeding, recurrent abdominal pain, nausea, and vomiting in children could present a diagnostic as well as therapeutic challenge. Meckel's diverticulum (MD) is one of the causes. The objective of the current study was to evaluate the feasibility and outcome of laparoscopic management of MD.

Methods

The clinical data of 33 children admitted with rectal bleeding and/or recurrent abdominal pain with no identifiable cause were reviewed over a period of 8 years. There were 23 boys and 10 girls with a mean age of 5.12 ± 2 years (range, 3-12 years). In 21 cases, MD was an incidental finding on laparoscopic appendectomy and symptomatic in 12 cases. Patients with rectal bleeding were subjected to upper gastrointestinal endoscopy; colonoscopy, and technetium Tc 99m-labeled pertechnetate scan (MS). All patients were subjected to routine laboratory investigations and diagnostic laparoscopy.

Results

Of the 1200 appendectomies, incidental MD was found in 21 (1.9%) patients and symptomatic in 12 cases. Upper gastrointestinal endoscopy and colonoscopy did not show a bleeding source in 7 patients presented with bleeding per rectum. Four cases showed a positive MS uptake. Of these, 3 were found on laparoscopy to have an MD. Three cases showed a negative scan. Of these, 2 had an MD. In 5 cases with recurrent abdominal pain nausea, vomiting, and abdominal distention, diagnostic laparoscopy revealed Meckel's diverticulitis in 3 cases and intussusception secondary to MD in 1 case. Laparoscopic Meckel's diverticulectomy and laparoscopic-assisted Meckel's diverticulectomy was done for 18 and 12 cases, respectively. Ectopic gastric mucosa was present in 13 cases (44%).

Conclusions

Laparoscopy is safe, cost-effective, and efficient for the diagnosis and definitive treatment of MD. Compared with conventional laparotomy, it has the advantage of precise operative diagnosis, less traumatic access, fewer intraoperative and postoperative complications, and shorter recovery period.     

Phytobezoar in Meckel's diverticulum: A rare cause of small bowel obstruction

IntroductionMeckel's diverticulum (MD) is the prevailing anomaly of the gastrointestinal tract, found in about 2% of the population; it rarely gives rise to symptoms and its discovery is usually accidental. Phytobezoar is a concretion of poorly digested fruit and vegetable fibres that is found in the alimentary tract and rarely can be the cause of small intestinal obstruction. Herein we report a rare case of intestinal obstruction due to phytobezoar formation into a MD.Presentation of caseA 50 year-old patient, was admitted to author's institution with an history of abdominal pain, nausea and multiples episodes of vomiting. Plain X-ray showed dilated small-bowel loops. Computed tomography (CT) revealed jejunal loops with air-fluid levels. The patient underwent explorative laparotomy where we found a giant Meckel's diverticulum, filled by a phytobezoar that caused small bowel compression. We performed a segmental ileal, resection, containing the MD. The histological exam confirmed Meckel's diverticulum.DiscussionBowel obstruction due to a phytobezoar in a Meckel's diverticulum is rare: only 7 cases have been reported in literature. MD complications are rare and phytobezoar is one of them with only few cases described in literature.ConclusionThe conventional x rays studies were inconclusive whereas abdominal contrast enhanced CT led to a definitive diagnosis. Explorative laparotomy or laparoscopy is mandatory in these cases.     

Laparoscopic Resection of Meckel's Diverticulum: Report of Two Cases

Symptoms of Meckel's diverticulum (MD) are present in only 4% of all cases and are often aspecific. The diagnostic modalities for the distal ileum are also often ineffective. We report herein two cases of MD's complications, intestinal obstruction and diverticulitis, which were managed laparoscopically. In both cases laparoscopy allowed the physician not only to make an accurate diagnosis but, at the same time, to perform a tangential resection of the MD.

Giant Meckel’s diverticulum compressing root of mesentery – A rare cause of ileal gangrene – Case report and review of literature

IntroductionMeckel’s diverticulum (MD) commonly presents as gastrointestinal bleeding in the pediatric population and intestinal obstruction in adults. There is no consensus for surgical excision of an incidentally diagnosed MD. We present a hitherto unreported vascular cause of intestinal gangrene due to MD.Case presentationA 16 year old boy was referred as an acute abdomen for tertiary hospital management. Clinical examination and CT suggested small bowel obstruction and emergency laparotomy was performed. A giant MD compressing the root of mesentery, causing critical occlusion of the ileal vessels and extensive ileal gangrene was found. The gangrenous bowel was resected and a jejuno-ascending colon anastamosis was done. Postoperative recovery was uneventful.DiscussionThis case report highlights an unrecognized complication of a giant Meckel’s diverticulum. There are no clear guidelines on the management of an incidentally discovered MD though certain studies recommend resection of an incidental MD in males and individuals less than 50 years of age or when the MD is larger than 2 cm or contains histologically abnormal tissue. Other meta-analyses do not recommend routine resection. MD has been identified as a high risk region for ileal malignancy and its resection usually has minimal morbidity. A valid consent for opportunistic resection of a Meckel’s diverticulum in any laparotomy would be discerning.ConclusionAppropriate opportunistic resection of an incidental Meckel’s diverticulum may prevent extensive surgical morbidity later. This case highlights the need to revisit guidelines for management of incidentally identified MD.     

A rare case of a strangulated Littre’s hernia with Meckel’s diverticulum duplication. Case report and literature review

IntroductionThe Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract present in approximately 1–4% of the population; the MD duplication is exceedingly rare with only a few reports of it. Here we present the firs case of a strangulated Littre’s hernia with MD duplication.Presentation of caseA 30-year-old male presented to the emergency room with clinical signs of small bowel obstruction, at physical examination, a right incarcerated inguinal hernia with erythema was found. We did a laparotomy, and two MD were found, one in the sac with ischemia, and the other 90 cm from the Bahuińs valve. A diverticulectomy of the ischemic diverticulum was done, and the other MD was left in place; the inguinal region was repaired with a Lichtenstein technique.DiscussionThe complications of the MD are 3–4 times more frequent in men, been an intestinal obstruction, hemorrhage, diverticulitis, ulceration, and perforation. A Littrés hernia is when the MD is found in the sac; this is seen in the inguinal region in 50% of the cases. The management of a Littre’s hernia is the resection of the MD; it could be done by an intestinal resection or by a diverticulectomy accordingly to the Park criteria.ConclusionAs to our knowledge, this is the first case of an incarcerated Littre’s hernia with duplication of a Meckel’s diverticulum.
